DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 418,785, dated January '7, 1890.

Application filed April 9, 1889. Serial No. 306,542. (No model.) i

To all whom it may concern.-

Be it known that we, CHARLES H. EVANS and CHARLES WILSON, citizens of the United States,'residing at Rockport, in the county of Knox and State of Maine, have invented a new and useful Improvement in Dumping: Cars, of which the following is a specification.

The object of our invention is to simplify and improve the construction of dumping-oars,

a perspective of ourimproved car in its nor-- mal position. Fig. 2 is an end View shoving the car-body tilted to one side to discharge its contents. Fig. 3 is a perspective view of the car-truck, the car-body being removed; and Fig. 4:- is a detached detail.

. A represents the main frame of the truck,

and B, B, and B are bolsters securely bolted thereto, one at each end and one about midwayof the truck. Each bolster is recessed at its upper edge, as shown at b, and in these recesses a bar 0, preferably semicircular in cross-section, rests. The rounded portion of the bar fits in the recesses,and it is cut away, as shown at c, to form shoulders on each side of the bolsters for the purpose of preventing end movement of the bar.

D is a car-body, firmly secured by bolts or. otherwise to the'bar C, the car-body resting on the flat'face of the bar. serves as a pivot forthe car-body, and is se cured to it in such position that the-body will be evenly balanced on the truck. The bolsters are beveled on each side of the recesses 19, as shown at b, to enable the car-body to tilt in either direction. The end bolsters B and I? are shorter than the end timbers of the main frame of the truck, and to each end of these bolsters is hinged a block E. These blocks are of such depth that when they rest on the end timbers of r the truck-frame their upper surface will be level with the flat surface of the bar C, and they will thus form a bearing or support for the car-body and main- The bar C.

tain it in a horizontal position. The blocks E are hinged to the bolsters B B in such a manner as to swing outwardly clear of the car-body when it is desired to tilt it, and when they are in position to support the car-body they are held in position by bolts 6, which ongage the. staples e in the end timbers'of the frame.

In order to prevent the car i body being thrown off the truck, straps F pass loosely around the ends of the bar C, and are firmly secured to the bolsters and the main frame of the truck. We prefer to use a car-body with swinging side board; but any other form of car-body adapted to discharge its contents sidewise may be used.

7 The operation will be easily understood. The car having been loaded and transported to the desired position, in order to discharge its contents, the bolts 6 are disengaged from the staples e at each end of the car on the side on which it is designed to dump the load. The blocks E are swung outward clear of the car-body, and the body can then be easily tilted, as it is balanced 011 the pivotal bar. C. It will be thus seen that the car can be easily operated to dump its load on either side, and also that on account of the broad supportingb'ase, formed by the hinged blocks E, it is not liable to tilt accidentally.

Having described our invention, we clai n1- 1. In a dumping-car, the combination, with the main frame of the truck and the opposite end and central bolsters and corner-blocks secured thereto and projecting upwardly therefrom, of the pivotal bar resting on said bolsters, the car-body secured to the pivotal bar, and the blocks hinged to the end bolsters, substantially as specified.

2. In a dumping-car, the combination, with the main frame of the truck and the bolsters secured thereto, said bolsters being recessed at their upper edge, of the pivotal bar resting in said recesses and provided with shoulders on each side of the bolsters, the car-body secured to the pivotal bar, and the supportingblocks hinged to the end bolsters, substantially as described.

3. In a dumping-car, the combination, with the main frame of the truck and the bolsters secured thereto, of the pivotal bar resting on said bolsters, the car-body secured to the pivotal bar, blocks hinged to the end bolster, and our own We have hereto affixed onr signatures bolts for securing said blocks to the main in presence of two witnesses. frame, substantially as specified.
